I run 28 or so with 75/25 and all wire sizes.

That "fixed regulator" is at 30, which is fine. Though I don't like the idea of no control over it (sometimes a little more is needed if there is some wind for instance) it seems like it would do the job for welding around the garage without a problem.

here's a pic of the package&here is a pic of the line with the gauges they gave me I'm using mixed c02 argon which line should I use?
ok pics won't upload so basically take a look @ the link should I keep it or use the traditional gauges?

The fixed flow regulator that is in the picture flow rate is 30cf which is a waste of gas and $$.

I find 14 works great with 75/25.

turn the knob on the front of the flowmeter clockwise until the gage reaches 20. Then you will really be impressed.

holy heck! I thought I had been doing great with flux coreI just I just set my new mig up with the bottle.First try I made a bead look semi pro .Im so impressed tax are so nice also 24 gauge & I didn't burn through!The only thing I can't figure is when I open the tank one on the gauges stays@ 0

Hummm maybe a pic or two of what you have could help us help you faster? I mig everyday on auto body work and the co2 argon mix works well but tends to be a bit more expensive than straight co2. I use straight co2 because I am going to be cleaning and grinding off any spatter caused by the Co2. Plus Co2 is a liquid. When welding you use the head pressure gas off the bottle which means you get about 3 to 4 times the product out of a co2 bottle than a argon co2 mix at about half the price!

Typically flow meters are used as a delivery valve. It screws directly to the argon/ co2 bottle with a #580 CGA threaded nut built on the flow meter. The flow meter typically has 2 gauges, one reads the gas delivery pressure and the other is tank pressure. The delivery flow should be between 15 to 25 cu,ft. per hour. Co2 on the other hand usually uses a pressure regulator as an delivery valve. It looks just like the flow meter and mounts on the cylinder the same way. The fitting on the standard size bottle is a 320 CGS threaded nut. They make adapters so you can run co2 on a flow meter, but not the other way around. Your mix is about 2300 psig in the bottle when full. The co2 is 850 psig when full so the regulator cant handle the higher pressure of the mix.

If what you have is .030 Id us it. if your welding on a car made after about 1977 or so the metal got much thinner so it wont take the same heat as an older car. What you will want to do is tack welds! Just a small spot on the seam then move a few inches away and do it again. If its a patch do this skip spot weld process until everything is filled in and it looks like one continues weld. If it ever gets too hot to hold your hand on the body just a few inches from the weld it is getting too hot! Stop and let it cool before welding any more! Be sure to keep skipping around to minimize the heat build up on any one area. Turn the machine down as low as you can and start adding wire feed speed and voltage until you get a good tack weld without burning through. Make sure there is no wind or fans on that can blow away your shielding gas. Hummm that should get you going on this beautiful Saturday. Good Luck

there's no gauge on it Ill post a pic

The thing about using the .030 wire is,, You have to run the machine a little hotter then you would to burn the .023. As far as what type of regulator you have,, I'm not sure on that machine,, But all you need to set the gauge at is around 15 l/m.. Hope this helps you..

need help bought a mig&dithced the flux core

So I just went & bought a auto arc 130 made by hobart its the same as the miller auto arc 130 or millermatic from what I was told.I'm gonna be using this only for body panels..its funny the other day I posted how for two years now Ive been using the flux core for my body panels and was wondering if I should upgrade.Well the following day the metal on this body was so thin data kept blowing holes through it.Ended up pulling the whole fender and I'm just going to replace it but besides that means something that would weld thinner stuff.
Ok will hear are my questions even know the booklet calls for traditional gauges this thing comes with the a fixed flow regulator kit.. well you gotta buy a separate but you get what I mean.Is is there anything I should know about this?Also I have .030 tips&wire. but can't find .024 tips&wire the guy @ cee Kay recommend it .023 so I got some well that we're good for welding thinner stuff? Or should I stick with the .030?Also as I'm new to using the bottle to I go wide open?Also isn't there a way to add a gauge so I can tell when I'm low?I bought a c02 argon set of gauges just incase
